I draw figures for my mathematical lecture notes using Inkscape (2019)

Cool. Your repos are so popular. The stars range from 300 to 1000, and the forks range from 50 to 200. I wonder what kind of audience you generally get, since they seem quite high for the niche.

Side question, I notice that you don't use UTM parameters for your submission link. I wonder if you know about it, and if yes, then why don't you use it? I also gather all my knowledge about this and ask in this question: [What would be the reasons for not using UTM parameters?](https://webmasters.stackexchange.com/q/144604/52079)
